BEDVSTEAD.

Specification oi' Letters Patent. Patqgnljed Jan. 31, 1922,

Application led November 20, 1920. Serial No. 425,307.

To all whom it may Concern Be it known that I, CHARLES HmnonnN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Bedsteads, of which the following is a specification.

This invention relates particularly to bedsteads in which the longitudinal` members, or side-rails, are detachably connectedV with the end standards. y

The primary object is to provide an improved connection between the side-rails and end standards, whereby the side-rails may be secured with the utmost rigidity and staunchness to the end standard, the conf nections nevertheless permitting the parts to be assembled and disconnected with ease and facility.

The invention vis illustrated, in its preferred embodiment, in the accompanyingdrawing, in which- Fig. l represents a brokenY perspective View of a side-rail of a bed, as constructed in accordance with the invention; Fig. 2, a broken perspective view of one of the up-V rights or posts of an end standard; Fig. 3, a broken longitudinal sectional view, showing the side-rail connected with the post, the section being taken as indicated at line 3 of Fig. l; Fig. 4, abroken horizontal se'ction taken as indicated a-t line 4 of Fig. 3; Fig. '5, a. broken horizontal sectional view showing a modification in which lthe tightening lever employed is made to swing in a horizontal plane instead of a vertical plane ,I and Fig. 6, a broken vertical sec'- tional view showing one of the posts of a wooden end standard, adapted for .use in connection with the invention.

Referring to Figs. l to 4, inclusive, 'A represents one of the posts of an end standard of a bed; B, one of the longitudinal sidemembers or side-rails of the bed; B, a bearing member which forms a slidable extension for the rail B; and C, means for shifting the members B and B with relation to each other to effect a tightening or vclamping action of the bearing member B against the corner-post of the bed. Y

The post A is shown as a tubular metal post provided interiorly, at the point of connection with the rail, with a reinforcing sleeve l. Through the tubularpost and the reinforcing member l is cut a T -slot 2, which has the enlarged upper portion 2a and the reduced lower portion 2".

The rail B is shown as an angle-form metal rail which is provided at its eXtremity with a transverse flange 3.v This iange has a tapped hole therein through which is screwed a screw-bolt 4, which is equipped with a lock-nut 5. The rounded head 4a of the screw-bolt is adapted to be passed through the enlarged portion 21L of the slot 2 and the head of the bolt will engage the reduced portion 2b of the T-slot when the rail is in the position with reference to the post which is shown in Fig. 3. Thus, interlockinof connection between the Ipost A and the rail B is provided. The rail B has its vertical flange equipped with an inwardly projecting lateral stud 6, which is adapted to serve as a cam-stud. v

The bearing-#member B is of U-'form cross-section, being provided with a top member and side-members1 and 7b. The side-members m-ay be of approximately triangular or truncated triangular form, as shown. The member B is further provided with a concave end wall' which is adapted to engage the rounded surface o f the corner post. This wall may be formed by extend-y ing the side flanges '7a and 7b and bending them into a transverseplane and then concaving them, thus forming the members 7C and 7, respectively. The whole member B may be thus conveniently for-'med of strong sheet metal. The shank of the screw-bolt 4 extends freely through a perforation in the members 7 c and 7d. The member IB embraces the end portion of the rail B and is adapted to slide thereon, the shank olf the screw-bolt 4 at the same time sliding lthrough the perforation in the members 7 'and 7d.

portion 8a. The head-portion 8 is journaled on a transverse stud 9 which has itsends secured to the side-members 2'a and 7b Vof the bearing member'B. The vertical flange of the rail B is provided with a longitudinal slot 10 through which'the rivet or Stud 9V extends. The lever C has its head portion 8 Vprovided with an eccentric or cam surface 8b which is presented upwardly and towards the cam-stud v6.

When the slidable bearing member B and the rail B are in collapsed relation, the stud or screw-bolt l may be entered readily through the Jlslot 2, after which the lever C may be swung to the position shown in Fig. 3, thus forcing the member B against the post L and forcing` the rail B in the opposite direction, so that the wall oit' the post is firmly clamped between the head ot the screw-bolt and the concave bearing surface of the member B. l/Vhen the handle 8 oi the lever is in the elevated position shown in F ig. 3, the cam-stud 6 rests in a slight recess 8C at the base or extremity ofthe ram surface 8l), and the lever will remain, by reason of the frictional engagement, in the locked position shown in Figure 3. When it is desired to separate' the rail Yfrom the end standard, it is necessary only to throw the handle 8a oit the cam-lever C downwardly, thus relieving the tension, after which the rail may be removed by lifting it and then withdrawing it.

In the modilication shown in lil ig. 5, vB2 represents a longitudinal rail; B3 represents a slidable bearing member similar to the 'bearing member B; and C represents a cam-lever adapted to siving in a horizontal plane. In this case, the cam-stud carried by they rail B is designated Ga; and the sidemembers 7a and 7b ot the slidable bearing member B3 have connected therewith a crosssmeniber il which is provided with a iorizontal slot in which is mounted the head portion ot the lever C, the head portion being connected with 'the cross-member ill by a pivot lla. The cam-lever is provided with a suitable cam l2 'for coacting with the cam-stud 6a. The parts are shown in locked position in Fig. 5. It the handle of the cam-lever be swung awayV from the vertical flange ot the rail B2, the parts will be released. y

Fig. 6 shows a Wooden corner-post A equipped with a socket-plate i3 which is provided with a T-slot 14'. lt is obvious that the socket-plate 1? may receive the head oit aV stud, such as the screw-bolt a, and the invention may thus be employed in connection with a bedstead having a Wooden end standard. Obviously, the shape ot the end Wall oic the slidable bearing member B may be suitable li'or a rounded post or for a post having a flat surface, as desired.

'The improved construction is adapted to provide exceedingly tight and staunch connections between the rails and end standards of a bedstead. Nevertheless, the parts may be readilyl assembled or disassembled.

The foregoing detailed description has been given for'clearness of understanding VonlyV and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as y broadly as permissible in View of the prior art..
